Bachelor of Science
Join nutrition experts and registered dieticians with careers in schools, wellness centers, grant-funded research studies, the food industry and nonprofit organizations.
Nutritional science is the study of nutrition and foods in health and disease throughout a person’s life. Students in this program are passionate about understanding the connection between food, nutrition, physical activity and healthy living.
The program provides a strong foundation in the sciences along with a wide variety of food and nutrition courses to prepare you to become a registered dietitian nutritionist (RDNs) or a nutrition professional, depending on which area of emphasis you choose: nutrition or dietetics.
The Nutrition emphasis combines medicine, food chemistry, cell biology and biochemistry with a focus on nutrition and foods. As a graduate with this degree, you may choose to enter the workforce directly or go to graduate school to gain an advanced degree in nutrition, food science, nutritional biochemistry, dentistry, nursing, physical therapy or veterinary medicine.
Courses include nutritional biology and metabolism, food science and safety, nutrition assessment, and therapeutic diets. Graduates in this major may also work as nutritional advisers in schools, wellness centers, the U.S. military or nonprofit organizations. Some of these jobs may require an advanced degree or certification, but students with a bachelor’s degree in Nutritional Sciences will have many paths toward their goals after graduation.
The Dietetics emphasis provides a strong foundation in the sciences along with a wide variety of food and nutrition courses to prepare you to become a registered dietitian nutritionist (RDNs) or a nutrition professional.
This emphasis is the first step toward becoming an RDN or a Nutrition and Dietetics Technician, Registered (NDTR), and it prepares you to work in disease prevention and management, community health and wellness, counseling, food science, and the food industry. Many careers in the fields of food and nutrition require or prefer the RDN or NDTR credential.
To become an RDN, graduates must complete an accredited Dietetic Internship. These programs have competitive admissions and can be started after graduation from a dietetics program. Following the internship, a national exam is required as the final step to earn the RDN credential.
The following courses are prerequisites for courses within this degree and are not offered in a fully online format. Students enrolled in this program will need to transfer in or obtain equivalent credit concurrently for these courses:
- CHEM 151: General Chemistry I (4 units) and CHEM 152: General Chemistry II (4 units)
- CHEM 241A: Lectures in Organic Chemistry (3 units)
- CHEM 241B: Lectures in Organic Chemistry II (3 units)
- MIC 205A: General Microbiology (3 units) and MIC 205L: Biology of Microorganisms Lab (1 unit)
- PSIO 201- Human Anatomy and Physiology I (4 units) and PSIO 202 - Human Anatomy and Physiology II (4 units)- Dietetics Emphasis only
The Dietetics emphasis at the University of Arizona is a nationally accredited Didactic Program in Dietetics by the Accreditation Council for Education in Nutrition and Dietetics (ACEND).
